Analysis on Controlling Oil Pressure Regulating Performance of Hydro-Viscous Variable Speed Clutch

Abstract

Hydro-viscous variable speed clutch has been widely used in starting and speed regulation of large load. In order to change the friction disc gap and the oil film thickness, converter was adopted in this paper to drive the pump to adjust the controlling oil pressure. The performance of pressure regulating of the controlling oil was analyzed and the characteristic curve of frequency-oil pressure could be acquired. The research showed that the controlling oil pressure can be changed by adjusting the frequency of converter. Besides, the slope coefficient and starting frequency of performance curve will be influenced by the leakage of hydro-viscous variable speed clutch and pump, the resistance of oil filter and the throttle valve opening degree.
